I think that this is a great book; I read it when I was about 11 kyu, and it improved my strength by two stones. It helped me not so much because I learned the specific tesuji in it (they're all useful, but don't expect to have them all down pat after a first reading) but because it was my first prolonged practice at reading, so once I was done with the book I was much better at reading than I was when I started, which paid off immediately in my games.
Don't worry about trying to finish the book - working through an entire book with as many problems as this one has is very taxing, so if after a couple of weeks you find that your brain doesn't want to do reading problems any more, switch to another book.
